System: NetBSD coral.primenet.com.au 1.2B NetBSD 1.2B (CORAL) #8: Fri Jan 31 17:11:02 EST 1997 root@coral.primenet.com.au:/src/netbsd/src/sys/arch/i386/compile/CORAL i386


>Description:
	/bin/ps.c sets up an errbuf of 256 bytes which it passes to 
	kvm_openfiles() - which at one point may like to
	strncpy(errbuf, .... , _POSIX2_LINE_MAX - 1)
	Result is bus error.
	This is with kvm.old but by quick inspection kvm does the same thing.

>How-To-Repeat:
	% ps 1 2
